* What is broadband?
In general, broadband refers to a wide band of frequencies available to carry data. By using this wide band of frequencies more data can be transmitted in a given amount of time.
The term applies to networks having bandwidths significantly greater than that found in telephony networks. Broadband systems are capable of carrying a large number of moving images or a vast quantity of data simultaneously. Broadband techniques usually depend on coaxial or optical cable.
* what are the advantages of broadband?
Fast, always on line, cheaper than dial-up, enables bigger files to be downloaded (video, music)
* what are the techniques available?
The breakdown of broadband technologies in December 2005 is as follows:
o DSL: 62%
o Cable modem: 31%
o Other technologies (e.g. satellite, fiber and fixed wireless: 7%
